Hernando Grande, Antonio ; Gálvez Alonso, Fernando ; García, Miguel A. ; Guinea, Francisco | Elsevier | 2020-02-15We analyze the contribution of the inhomogeneous magnetic field induced by an electrical current to the spin Hall effect in metals. The Zeeman coupling between the field and the electron spin leads to a spin dependent force, and to spin accumula[...]![]()

García Fernández, Guillermo ; Guerrero Rojas, Jesús ; Llanes Estrada, Felipe José | Elsevier | 2017-02The gauge symmetry of the Standard Model is SU(3)_(c) x SU(2)_(L) x U(1)_(Y) for unknown reasons. One aspect that can be addressed is the low dimensionality of all its subgroups. Why not much larger groups like SU(7), or for that matter, SP(38) [...]![]()

García Fernández, Guillermo ; Guerrero Rojas, Jesús ; Llanes Estrada, Felipe José | Elsevier | 2019-12We point out an error in our previous work, that affects the claims made for the special Lie groups and for the SO(N-c) groups of lowest dimension, which are therefore retracted. Our earlier results stand for larger-dimension SO(N-c), as well as[...]![]()
